MEASURING SYSTEM OF PULSE TRANSIT TIME AND METHOD THEREOF

摘要

PURPOSE: By using the analog signal processing circuit the pulse wave transmission time instrumentation system and method thereof extract the feature information needing calculation from the signal of PPG and ECG PTT. CONSTITUTION: An ECG electrode(40) outputs the electric signal by detecting ECG. The ECG detection circuit(42) amplifies the signal it electricals, detected with the ECG electrode. The PPG sensor(50) outputs the electric signal by detecting PPG. The PPG detection circuit(52) amplifies the signal it electricals, detected with the PPG sensor.
